目的为城市园林树木、小区绿化、公园等白蚁防治工作提供理论基础和实践指导。方法抽样调查常德市41家园林苗圃基地以及5个公园的53个树种5 893株树木。结果 54.7%的调查树种发现白蚁危害,调查树木总白蚁危害率为24.4%,82.9%的园林苗圃基地、80%的公园树木均遭受到了不同程度的白蚁危害。白蚁危害率较高的树种为香樟(76.9%)、大叶樟(64.1%)、油茶树(53.8%)、桂花(39.7%)。园林苗圃树木主要白蚁危害种类为黑翅土白蚁,其次为黄翅大白蚁和台湾乳白蚁。结论园林苗圃白蚁危害具有普遍性,树龄越大危害率越高。深入分析园林树木易受白蚁危害的原因,对园林树木白蚁危害的综合治理提出了建议。

Objective To provide some theoretical basis and practical guidance for termite control on trees in urban garden,residential green area and parks. Methods 5 893 trunks of 53 varieties of trees in 41 gardens and 5 parks of Changde City were surveyed. Results 54. 7% of tree species and 24. 4% of trees in total survey samples,82. 9% of nursery bases and 80% of the park trees were infected by termites. In all tree species surveyed,Cinnamomum camphora was most seriously damaged by termites with the damage rate of 76. 9%,followed by Cinnamomum septentrionale,Camellia oleifera and Osmanthus fragrans,64. 1%,53. 8% and 39. 7% respectively. Major hazard species of termites to trees of nursery gardens was Odontotermes formosanus,followed by Macrotermes barneyi and Coptotermes formosanus. Conclusion The termite damage to trees in nursery garden was universal and the degree of damage was often age-related,it was found that the higher the tree ages the greater the hazard ratio. Moreover,the causes of termite damage to the garden trees were also analyzed and discussed,and some advices of integrated management to garden trees are proposed.
